Abstract: With the widespread application of large-diameter steel pipe piles in offshore wind power construction,driveability analysis has played an important role in predicting and solving technical problems and safety hazards in pile sinking construction. By considering the analysis and research on the change of soil bearing capacity around piles under the influence of excess pore water pressure, a new method for obtaining soil parameters in the process of driveability analysis is proposed, and the pile sinking process of a large-diameter steel pipe pile in an offshore wind power plant is carried out. Application of driveability analysis, the application results show that the prediction of pile bearing capacity, maximum stress value of pile body, final hammer penetration and other data of driveability analysis is very close to the actual measured value, which verifies the consideration of excess pore water, The analysis of the driveability of large-diameter piles under pressure is more accurate, and can provide scientific technical guidance for the feasibility of pile sinking construction.
